Detailed Description

This is an important class for using LLVM in a threaded context. It (opaquely) owns and manages the core "global" data of LLVM's core infrastructure, including the type and constant uniquing tables. LLVMContext itself provides no locking guarantees, so you should be careful to have one context per thread.

Member Function Documentation

void LLVMContext::emitError	(	unsigned	LocCookie,
		const Twine &	ErrorStr
	)

emitError - Emit an error message to the currently installed error handler with optional location information. This function returns, so code should be prepared to drop the erroneous construct on the floor and "not crash". The generated code need not be correct. The error message will be implicitly prefixed with "error: " and should not end with a ".".

getMDKindNames - Populate client supplied SmallVector with the name for custom metadata IDs registered in this LLVMContext.

getHandlerNames - Populate client supplied smallvector using custome metadata name and ID.

void LLVMContext::setInlineAsmDiagnosticHandler	(	InlineAsmDiagHandlerTy	DiagHandler,
		void *	DiagContext = 0
	)

setInlineAsmDiagnosticHandler - This method sets a handler that is invoked when problems with inline asm are detected by the backend. The first argument is a function pointer and the second is a context pointer that gets passed into the DiagHandler.

LLVMContext doesn't take ownership or interpret either of these pointers.
